Abstract

This work studies the effect of incorporating fluorescent organic extracts and oxide zinc nanoparticles in silica xerogel composites prepared by the sol-gel method, under different condition of preparation, which confer different optical and structural characteristics to product. The samples at room temperature and heat-treating at annealing temperature were studied using infrared spectroscopy, fluorescence, X-ray diffraction and differential temperature analysis.

Keywords: Sol gel; Fluorescence; Chlorophyll; Zinc oxide nanoparticles.
